This invention relates to a bumper for vehicles and more particularly toa novel end lcap and clamp for the front of the bumper.'

The object of the invention is to provide a .n bumper having verticallyspaced front bars the bumper bars are securely held, which is neat inappearance and which provides a relatively smooth rounded end for thebumper. In the drawing which forms a part of t-his specification Fig. 1is-a top plan view of a bumper with the ends constructed in l.accord-` Aance with my invention; Fig. f2 isan enlarged fragmentary detail view ofthe end portion of thebumper taken on line 2,-,2 of Fig. 1; Fig. 3, is avertical sectional view through the sleeve showingthe methodin which.thebars 25 are held therein; Fig. 4 is a sectional view :through ytheyhlllfflpertaken on line of Fig. 2; Figj is .a top plan view of adifferent form of bumper on which a slightly modified form of end`sleeve is used.; F ig. 6 is an enr30 larged fragmentary detail of theend -o i' the vbumper AShown in Fig. 5, Athe vsleeve being shown insection, ,and Fig. 7V is a ysectional view takenOIl the line 7-,7 ofFig. k6.

Referring Ito the drawings in which likeref- 5/erence numerals designatelike partsin the kseveral views, the bumper vshown` in Figs. lto ,4Cinclusive which embodies the end constructionof my invention comprisesan impactsection desigggnated generally by the reference Y .4o numeral`10, ,and a back bar or anchor-bar ll by which the bumper is secured tolthe frame horns 12 of a vehicle in the `usual manner by clamps 14. v

The impact section 10 is made .up .of .two

A1&5 vvertically spaced bars lsecured to each Aother andto thecentralportion of the `backbar bly means of a center .clamp `17 Lof any.desired constr'nction. In the'ufo'rm illustrated in Figs. 1

to 4 inclusive thefro'nt bars 16 *have their 5.0 .front vedges"beveled`,als at `-lanid inwardly' of '-.bration of their ends the bars arebowed as at 19 so that the ends project slightly toward the rear. Theends `oit lthe rear bar l1 are bent toextend parallel with the ends ofthe front bars and to contact .with the rear faces thereof.. -T'he ends55 of ythe front .bars 16, it will .be noted, are rounded .as vat 20 andover the ends f the front and rear bars a sleeve .or kcap Afits.

The front face of the cap y25 is made .to conform to the shape of thefront sides of Ithe bars 16 SO jthat theinner Itapered portions '2 6' ofthe wall provide seats for the bars -16 l.and hold them ifnspacedrelation. The rear face of the Cap Ais provided at its centerr with anoutwardly v.bowed portion 27 providing a `seat .e5 f crthe end of .therear. bar 11. The cap25 .is

, so shaped and proportioned that .the ends r.of Y

the ,bars 16 .and llfwhen in close engagement lit snugly therein, andthe .outer end 28 oitthe cap is rounded to provide a smooth andneat endfor the bumper.

f The front and rear sides of the .cap are provided centrally .withaligned apertures .to receive a .clamping .bolt 3.0 which y.passesthrough an aperture in the `rear bar l1 and 7.5 holds the Y.parts'inassembled relation. The metal from which the cap 25 is constructed isysufficiently flexible so .that when thel nut 31 4on the b o'lt 30 :istightened the bars116 and a 11 yare tightly clamped together and-between430 the front yand rear wall of the cap. To pre- Vent longitudinalmovement .ofthe front bars in .the cap, each bar 1.6. is provided nearits end and 4on its inner y'edge with an arcuate Yor other shaped notch35 Ioppositethe 'rboltd .-3.5 In the recess providedby the opposednotches 35 a round or other shaped washer or aller .member dits, thewasher being received on the bolt and clamped in place between the'front side .of the ycarp 'front side of tbe rearbar y"bythenut 31. `Alock .washer 32 may, of course, be .used to .prevent 'thenut .from.working lgose onthe belt .under the .vi-

the .vehicle on which Ithe bumper isused. f ,9,5

The .washer 36 is of suchathick-ness as to fibe .clamped between the.fr-ont "sideboffthe .sleeve 25`andthe-'backbar-1l when the mit V totightly clamp the front bars 16 before it is limited in its inwardflexing by the Washer 36.

VIn Figs. '5 to 7 inclusive a modified form of clamping sleeve is shown,which is used on the type of bumper wheretheback bar Y is not attachedto the ends of Vthe front bars-V vrounded front faces.

VIn this form of bumper the impact section to the rounded face ofthebars so as to pro-` vide'sockets 47. `The back side 48 of eachl isleeve is straight. A bolt 5 0 passes Vthrough l the.; central portionof the sleeve between the bars 1-1A so thatwhen the nut 51 is tightenedthe barsare clamped tightly between the front and back sides ofthesleeve; Each bar 4() is notched as vat 52 and intheopposed notchesV52 i's receiveda filler member 53l through which'the bolt V50 passes,which filler member prevents longitudinal movement of the cap onth'ebars as long as the bolt 50 is in place. In this form the sleeve issufficiently 'flexible to permit the Vsides-'tobe clamped tightly on thebars by the bolt and nut;

Y V-The back bar 55"in" this formof bumper otherproviding Ushapedresilient attaching Vproperly positioning theVV ends of saidi bars,boltmeans passing through said sleeve and back bar and betweenthe frontbars securely'V is secured intermediate'of its 'endsto the frame horns12 Yof the vehicle by lclamps 14,

and the ends of the bar are bent toward each portions'r. ATothe freeends 57 of the bar 55. the impact section 10 of the bumper is secured bysuitable clamps 58. In ythis type -of bumper the ends of the impactsection 10 project'outwardly beyondthe back bar.)

It isofcourse obvious that theback bar of the bumper may be of any shapeor form to ymeet the requirements of the car Vupon which itl is to Vbeattached, and the impact :section may be made of -moreithan the twoVbars withoutV departing from the spirit of my invention and thescope oftheappended The cap yeither in the" form shown in Figs. .1 to 4or in theform shown in Figs. 5 `to 7 vwith the onebolt and filler member provides[a rigid connection for the ends of the bumper I claim is Y Y 1.
